Jerry,

Which style of frame do you have, the ones with the studs or the one with the holes? A word of warning for the ones with the holes, be very careful with them. If the screws are rusted and stuck in the holes, the frames can break at the holes, especially the middle set. You'll the be faced with finding someone capable of welding them back together. Not an easy task. I don't have a solution except for soaking in penetrating oil before attempting to remove the screws.
